Hello Vaibhavi

Please see the model 224 Quick Reference Guide. On page 18, it states that the negative going trigger out pulse happens at the end of a dwell time. The 224 Instruction Manual page 2-15 states that the external trigger output is present only when a source value has completed the increment or decrement.

If you want to programmatically send a trigger, you may consider using the digital out signals.
